Design and Analysis of a 2D-Photonic Crystal Fiber Structure with Ultra-Flattened Dispersion and Single Mode Operation Over a Wide Range of Wavelength

A photonic crystal fiber (PCF) presents a new way to guide light. The air holes in the fiber work as a cladding, but provide much more flexibility in the design. In this work, the plane-wave expansion technique for generating and analyzing photonic band structures is used. The simple 2D XY array with a hexagonal cross-sectional pattern of air holes in a silicon fiber is analysed for calculating parameters such as mode effective index, dispersion and single mode operation over wide wavelength range. The results of a design sample presented in this article, showing the better result to analyze this new class of fiber. This fiber can be used for biomedical application, spectroscopy, and super continuum generation.
